To the Editor:—
The first diagnostic uses of ultrasonography in ophthalmology were described by Mundt and Hughes in 19561 and Oksala in 1957.2 Ultrasound has since been shown to be useful, diagnostically, in determining the axial length of the globe, localizing intraocular foreign bodies, and in identifying various intraocular and retrobulbar lesions.The history, theory, and techniques of ocular ultrasonography have been reviewed.3 Oksala first showed the value of ultrasound in the diagnosis of a posteriorly luxated lens4 and explored the effects of the lens on the ultrasound field; these included dispersion, higher absorption, and higher velocity than the surrounding ocular structures.5 He also demonstrated that multiple echoes may arise from a cataractous lens.6However, the ultrasonic diagnosis of anterior lens dislocation has not previously been reported. This may be of use when a cloudy cornea or anterior chamber make visual diagnosis difficult. This
